LOCK HASP Filed Nov. 19. 1930 2 Sheets-Sheet 2 Patented Sept. 4, 1934 UNITED STATES LOCK HASP Abraham Levine, Elizabeth, N. .L, assignor to Presto Lock Corporation, New York, N. Y., a corporation of New York Application November 19, 1930, Serial No. 496,626 11 Claims. (01. aez-zsn My present invention relates generally to looks and more particularly to looks employed for brief cases and the like and in which a hasp member carried from one part is arranged to engage I a locking member carried by another part to secure the parts in associated relation.

One of the objects of my invention is the provision of a new type of hasp structure.

Another object of my invention is the provision of a new manner of stamping a blank so as to provide a hasp.

Another object of my invention is the provision of a hasp having a name plate associated therewith.

It is still a further object of my invention to provide a new and improved arrangement in the locking member for holding the plug or bolt thereto in its sliding relation for latching and unlatching purposes.

For the attainment of these objectsand such other objects as may hereinafter appear or be pointed out, I have illustrated an embodiment of my invention in the drawings wherein-' Figure 1 is a front -'elevational view of my new lock in position on a brief case; p

Figure 11 is an enlarged fragmentary view of the lock parts during a stage of its assembly;

and

Figure 12 shows a stamping such asused for my look, before assembly thereto.

Upon viewing Figure 1 of the drawings, it will be observed that my invention relates to the type of lock which is provided withahasp 10 secured as for example to the 'flap of a brief case and arranged to'engage with and lock'to a locking member 11, secured to the frontfold of the briefcase. The details of the hasp construction reference will be made further on. The cuts 21 and-the manner of its manufacture are shown in Figures 2 to 6 and the details of the locking member and the manner of its assembly are shown in Figures 7 to 12. I will first describe the former. I 66 In Figure 6, I show a blank of sheeted metal out so as to provide the halves l5 and l6to be bent'into' parallelism along lines 17 and 18 to provide the two walls 19 and 20 of the hasp of Figures 4 and5. To facilitate the bending operation,the blankof Figure 6 may be scored along lines 17 and 18 although this is not necessary as this bending can be done without the scored lines.

'A hasp of the character herein referred to is generally provided with a perforated projection to enter anopening in the locking member so as to receive a locking element through the perforation in the hasp projection. This, hitherto, has generally been attained by securing to the hasp a relatively rigid perforated member which projects outwardly from the face of the hasp and which is secured thereto as by a welding or riveting operation. In accordance with my invention as herein-disclosed, I attain the same results in a more effective manner by a stamping operation and this I will now describe, in connection with the blank of Figure 6, and the finished hasp of Figures 2, 3, 4, and 5.

The blank of Figure 6 is provided within the general contours of the part 15 with the two parallel cuts 21 and 22. The upper ends of these cuts are connected by the oval shaped cut 23, thus providing two extensions or ears to which and 22 extend preferably in the opposite direction into the webbing connecting the two portions 15 and 16 or lnother words into the material between the lines 17 and 18. Within the parallel cuts, 21 and 22, and closely adjacent and parallel to the line 1'7, the part 15 is cut away to provide the elongated opening 25.

I will now describe how either before, during or after the operation of bending the parts 15 and 16 of the blank 6 into substantial parallelism to the hasp of Figure 4, I provide the interlocking element of the hasp by merely a bending operation. Upon viewing Figure 4, it will be ob-. served that the part defined-by the cuts 21, 22 and 23 and'which part will hereinafter be referred to by the reference character 24, has been doubled back upon itself transversely, and intermediate of the ends, of .the side cuts, 21 and 22, so as to give the substantially parallel portions 25 and 26 and to provide in the face 19 of the hasp the Ru larged opening 28, (see Fig. 5) and will be brought into opposition to the narrower opening 27, and the projections or ears 30 into contact with the inner surface of the wall member 19, and therefore will serve to hold the parts and 26 generally in a position such as shown in Fig. 4 of the drawings. The position of the opening 25, in the part 25, is shown very clearly in Figs. 2 and 3.

The hasp can be secured in position over the edge of the flap of a briefcase or any similar article by any preferred or desired means such as prongs 35. In Fig. 2, I have shown the hasp of Figs. 4 and 5 secured in position about such edge and in this figure, A is applied to the leather flap of a briefcase and upon carefully viewing this figure, it will be observed that the member 29 will be locked between theinner surface of the member 19 and the flap of the brief-- case so that the elements 25 and 26 which will define the locking element of the hasp will not only be locked in position but will be given considerable rigidity and will serve all purposes of the locking member hitherto employed and yet will have sufficient yieldability so as to provide for any inaccuracies in manufacturing or assembling process or for any warping or distortion of the parts.

I will now describe my arrangement for forming from the part 16 of the blank of Figure 6, the name plate holder to which the reference character 30, has been generally applied in-Figure 1. This name plate comprises an upper half 31 and a lower half 32, duplicates of each other but in reversed position to each other. The part 31- comprises a portion of the materialbent .out of the plane thereof so as to provide the end wall 35' at the left, the top wall 36 and the overhanging front wall or face 37. These walls define a channel which is closed at the left and on the top and which is open at the right and at the bottom for reasons that will be pointed out. The part 32 is similarly provided with an end wall 38 at the left, a wall 39, which, however, here is at the bottom, and a front wall 40, which between them define a passageway which is also closed at the left but open at the right but with respect to the part 32 is also open toward the top. These raised portions 31 and 32 are generally U-shaped with the legs of the U in vertical alignment and spaced slightly apart. Due to the U-shape of the members and to-the spacing of the legs, an enlarged exposed opening is provided.

A name plate such as shown at B in Figure lis inserted at the right so as to bring it below the overhanging walls 37 and 40 of the members 31 and 32, until the left. hand end of the name plate strikes the left hand walls, 35 and 38; The name card can be removed by moving it in the opposite direction and in this operation is assisted among other things by the spacing of the legs above referred to.

The name plate holding construction above described is formed from the part 16 of the blank in the manner shown in Figure 6. This blank is out, through along the full lines and 46 in said figure and then is bent upwardly along the dotted lines 47 and 48. The cuts 45 and 46 each comprise two spaced horizontal cuts in horizontal alignment, connected at their adjacent and inner ends by an intermediate U-shaped cut and extending upwardly from the outer end of one of the horizontal cuts, as for example the one at the right, is a vertical out. The material between cut 45 and the dotted line 47 and between the cut 46, and the dotted line 48, when bent upwardly out of the plane of the part 16 will give the name plate holder the conformation described above.

My preferred process for stamping the blank of Figure 6, then forming therefrom the hasp construction of Figure 4 is as follows:

In the first operation, the blank of Figure 6 is cut out in all respects as shown in Figure 6,

except as tothe cuts 45 and 46 which are made together with the second or forming operation.

The second step comprises the simultaneous performance of the following: (a) the cuts 45 and 46 are made in the section 16 and the material between each and the lines 47 and 48 respectively is bent up tocomplete the nameplate holder; (b) the parts 24 and 29 in Figure 6 are bent generally as shown in Figure 4, and (c) the securing prongs 35are bent inwardly at an angle to the blank.

In the third and final operation, the hasp is doubled upon itself and the locking prong made up of the elements 25, 26 and 29 given its final position of Figure 4.

Upon viewing Figure 1 of the drawings, it will be observed that the name plate appears on that face of thehasp which is exposed to view and the locking element of the hasp is at the back thereof as shown in Figure 4. The parts 25' and 26 are so dimensioned and spaced as to be receivable within any of the openings 50 of the lock member 11 to bring the opening 25 in the path of one of the projections'51 carried by a reciprocat ing bolt 52, (see Figs. 8 and v9). The bolt is mountedfor reciprocation within the lock casing 11 and is spring pressed into locking position and is moved into hasp releasing position by operating knob 53 (see Fig. 7), by mechanism which may be of the conventional type and therefore is not shown except as far as it is indicated in Figure 8 in dotted lines.

I will now describe my novel arrangement for holding the locking bolt 52 in position against the inside face of the locking casing 11 so as to permit of its aforementioned reciprocation.

Upon viewing Figs. 11 and 12 of the drawings, 3;;

it will be observed that the face plate 11 of the locking member, by a stamping operation or the like, has material removed at spaced points thereof as shown at 56 to leave the tongues 5'7 and 58,

which tongues are separated from the body of the j 51 and the cutout portions 62 and 63 on either side of each of said tongues.

In assembling the bolt 52 with the faceplate, it will be understood that, where, as in the instant case,ithree locking positions are to be provided, the face plate will be provided with the three openings and with the three groups of projecting tongues 57 and 58. The parts are so dimensioned that when the bolt 52 is positioned against the inner face of the face plate 11 the three groups of tongues 57 and 58 will be received each through a cut out portion 62 or 63 of an opening 61 of the bolt, and the side walls of these portions 62 or 63 will be adjacent to and will be guided by the outer faces of the widened parts 5'7 and 58 of the upstanding fingers 5'7 and 58. The height of these widened parts is substantially equal to the thickness of the bolt 52. The projecting finger portions 58" and 57 can then be bent each outwardly and downwardly to contact with the outer face of the outer surface of the bolt 52 so as to keep the bolt down in contact with the inner face of the face plate 11 and at the same time to permit of the relative reciprocation of the bolt with reference to the face plate. This reciprocation will be limited by the front and back walls defining the opening 60.

It will be understood that the bolt 52 is intended to be locked by suitable locking mechanism indicated in Figure 8, but not shown in detail, as it may be of any well known type suitable for the purpose.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is 1. A hasp for a lock comprising two oppositely disposed walls integrally united at one end and a lock engaging element carried by one wall, said element comprising a section formed integrally with and extending out from one of the walls, said section being doubled back upon itself to provide superimposed parts, and an opening in one of said parts adapted to receive a locking element therethrough.
